Before you start, you will need a JVM (Java Virtual Machine)
which conforms to the Java 1.6 (or newer) specification.
If you followed the Hello, World
instructions for COS 126, you already have it.
Otherwise, go to java.com and click the
Free Java Download button.

Click the icon to download the jar file; launch the jar file
either by double-clicking the icon
or by typing "java -jar toy.jar" at the command line.

Q & A

Q. Sometimes 'Reset' clears stdin, and sometimes it
doesn't. How does Visual X-TOY decide when to clear stdin and when
not to?A. Editing stdin in 'Edit Mode' changes the state to which
stdin resets, whereas editing stdin in any other mode only changes
the current state of stdin.

Q. When I open up files, sometimes Visual X-TOY opens a
new window, and sometimes it reuses the current window. How does
Visual X-TOY decide when to reuse the current window?A. Whenever you open several files at once, Visual X-TOY
always opens new windows. However, when opening a single file,
Visual X-TOY will reuse the current window if and only if the file
has not been changed since it was last saved.
